Title: Delay line
IPC: H03H9/125
Filed: 1964-05-29
Abstract: 1,063,881. Delay lines. FRIDEN Inc. May 29, 1964 [Aug. 13, 1963], No. 22466/64. Heading H3U. A transducer for a delay line is constructed so as to correct for the distortion imposed on the signal by the line and to derive a short, sharp output signal. As shown, Fig. 1, the delay line comprises an input transducer having magnetostrictive ribbons 12 attached to opposite points of a wire 10 and surrounded by coils 14 biased by magnets 16, the other ends of the ribbons being clamped in rubber pads 18. Thus an input signal 36 (Fig. 3, not shown) applied to the coils 14 imposes a couple on the wire 10, which wire (arranged in known manner in the form of a coil) transmits the mechanical signal to a further pair of magnetostrictive ribbons 22 comprising the output transducer, and an output signal is induced in the coils 24. In order to correct for the distortion and obtain a sharp output signal 34 (Fig. 4, not shown) the coils 24 are long and have a varying sensitivity along their length obtained by varying the density of the winding. The sensitivity profile 33 is shown in Fig. 5 and is similar to the pattern of the mechanical strain wave 33 (Fig. 4, not shown) produced by the input signal in the ribbons 22 and is derived from that pattern. As shown in Fig. 2, each coil 24 includes four sections 24a, 24b, 24c, 24d having stepped formations so that the greatest turn density occurs near the central portions, the four sections corresponding to the negative and positive swings a, b, c, d of the profile 33. The various rectangular blocks, e.g. b1, b2, b3 denote the winding sections. In modifications (Figs. 8-12, not shown) the plurality of coil sections are similar and the varying sensitivity is obtained by transistor amplifiers connected to the sections and adjustable to produce the desired profile.

Abstract: Alkylchlorosilanes of the general formula RaClbHcSi wherein a+b+c equals 4 and a is 1, 2 or 3, b is 1, 2 or 3 and c is 0 or 1 and R is alkyl are prepared by reacting an alkyl chloride with a mixture of a chloride of zirconium and finely divided silicon.  Specified alkyl chloride are methyl and ethyl chlorides.  Chlorides of zirconium, preferably used in an amount of 0.1 to 3.0% by weight based on the weight of silicon include ZrOCl2, ZrOCl28H2O, ZrCl2, ZrCl3 and ZrCl4. Hexachlorozirimates may also be used, e.g. Y21ZrCl6 or Y11ZrCl6 where Y1 is Li, Na, K, Rb or Cs and Y11 is Ca, Mg, Sr or Bn. In addition, Y1 may be Ag or Cu and Y11Zn, Ni, Cu or Fe.  The zirconium chlorides may be mixed with the silicon in solid form or as a solution in water or an organic solvent, e.g. CCl4.  The silicon may be in the form of an alloy containing, e.g. 80 to 98.99% by weight of Si, 1 to 19.7% of finely-divided copper or activated copper compounds and 0.1 to 0.3% by weight of aluminium and may also contain up to 10% by weight of Fe, Mi, Co, Sb and traces of B or Ge.  In addition, 3 to 10% of cuprous chloride may be added to the finely-divided silicon at least 50% by weight of which have particle diameters of below 0.3 mm., the remainder being below 3.0 mm.  The alkyl chloride is passed through the finely-divided silicon in the form of (a) a fluidized bed, or (b) a dispersion in a high boiling mineral oil, at 200-500 DEG  C. and 0.5 to 5.0 atmospheres pressure. In Examples (1) and (2) the products are fractionated to provide up to 28.4% yield of alkylhydrogendichlorosilanes together with (CH3)3SiCl, CH3SiCl3, (CH3)2SiCl2, SiCl4 and unreacted CH3Cl.

Title: Improvements in control mechanism for motor vehicles
Filed: 1932-08-15
Abstract: 398,635. Fluid-pressure brakes. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. Aug. 15, 1932, No. 22830. Convention date, Aug. 15, 1931. [Class 103 (i).] According to one feature of the invention in a vehicle having a clutch servomotor and a brake servomotor utilizing the vacuum in the engine induction pipe, the throttle, clutch, and brake are all controlled by a single member. According to another feature, in a vehicle having separate means for actuating the throttle, clutch, and brake, or having a poweroperated clutch and a power-operated brake, a single driver-operated member when moved in one direction operates the clutch and throttle, and when moved in another direction operates the brake. In the construction, shown in Fig. 1, a clutch pedal 30 can be operated by a servomotor 34 connected by a pipe 40 and valve 38 to the induction pipe 10. The brake pedal 80 can be similarly operated by a servomotor 90 controlled by a valve 96. The valves 38, 96 are operated by a two-part accelerator pedal 22 which also controls the throttle 12. The heel-part 26 of the pedal has an extension 108, Fig. 2, connected by a wire 104 and spring 106 to the brake-controlling valve 96 which is similar to the clutch controlling valve 38, Fig. 4. When the part 26 is depressed by the driver's heel the wire 104 is pulled, thus closing an inner valve 57, Fig. 4, on its seat in an outer valve 62 and moving the latter valve also so as simultaneously to close air ports 60 and open a connection between the servomotor 34 and the induction pipe. The servomotor 34 is thus energized and the brakes applied, this action being assisted by the direct pressure of the part 26 on the brake pedal 80. The spring 106 in the connection between the part 26 and the valve 96 allows further movement of the part 26 after the valve has been operated. The throttle is opened and the clutch engaged by depressing the toe-part 24 of the pedal. In the construction, shown in Fig. 9, the clutch and brake levers 210, 212 are entirely below the footboards, only one control pedal being provided. Modifications are described in which (1) Fig. 6 (not shown), the accelerator pedal is in one piece, its toe-part controlling the throttle and the brake and clutch valves, and its heelpart acting directly on the brake lever ; (2) Fig. 10 (not shown), a single hand-lever is provided with lost-motion connections to the clutch and brake levers so that it first disengages the clutch and then applies the brakes ; (3) Fig. 11 (not shown), the accelerator pedal has no direct mechanical connection with the brakes, but is so situated near the brake pedal that the driver can rest the toes of one foot on the brake pedal and the heel on the heelpart of the accelerator pedal, so that he can simultaneously apply the brakes by direct foot pressure and by power.

Filed: 1946-07-31
Abstract: 625,980. High-frequency electric filters. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. July 31, 1946, No. 22865. Convention date, June 16, 1943. [Class 40 (viii)] A high-frequency filter in a wave-guide is formed by introducing into the guide a transverse apertured partition, measuring its reflection coefficient and dephasing angle #1, and then introducing a second transverse partition with an aperture adjusted to produce a reflection coefficient equal to that of the first partition, measuring the dephasing angle #2 of this second partition, and separating the two partitions by a distance " d " determined from the expression 2#d/#1 = #1+#2/2, #1 being the wavelength it is desired that the filter shall pass. In the arrangement shown, the partitions 2 and 6 are provided with slot apertures and their distance apart is adjusted by means passing through a slit 5 in the wave-guide. By placing two such filters in succession in a wave-guide, and tuning them to slightly different wavelengths a bandpass filter is produced.

Filed: 1937-08-23
Abstract: 482,035. Hydraulic signalling apparatus. GIERS, C. A. DE. Aug. 23, 1937, No. 23086. Convention date, May 21. [Class 118 (ii)] In a system for transmitting indications by using sylphons, an additional pair of sylphons are provided between transmitting and receiving apparatus to compensate for temperature variations. In normal working, if the pointer 54 is moved to the left, sylphon 30 is compressed and sylphon 32 expands. The compression of 30 is communicated through pipe 100, sylphon 78 and pipe 102 to expand sylphon 34 whilst the expansion of sylphon 32 is communicated through pipe 106 sylphon 76 and pipe 104 to compress sylphon 36. The result is that pointer 64 is moved to the right an amount corresponding to the movement of pointer 54. If the temperature of the oil in the system changes, the change in volume of the fluid causes sylphons 76 and 78 to expand or contract by the same amount, both pipe lines containing the same amount of liquid, and this causes arms 88 and 90 to swing idly about fulcrum 92 without having any effect on the functioning of the system or the relative positions of pointers 54 and 64.
